Subject [jira] Commented: (PIG-170) Memory manager spills bags in the wrong order
Date Sat, 29 Mar 2008 07:58:24 GMT

Amir Youssefi commented on PIG-170:
-----------------------------------

Now I am investigating whether this failure is directly related to PIG-170 or it's cluster-wide
issue happening because we spill more data to Disks.

> For optimal performance, we want to spill the largest bags first. This is not what is
happening right now and could be causing some of our memory issues.
